<communications> A communications paradigm in which packets (messages or
fragments of messages) are individually routed between nodes, with no previously
established communication path. Packets are routed to their destination through
the most expedient route (as determined by some routing algorithm). Not all
packets travelling between the same two hosts, even those from a single message,
will necessarily follow the same route.
The destination computer reassembles the packets into their appropriate
sequence. Packet switching is used to optimise the use of the bandwidth
available in a network and to minimise the latency. X.25 is an international
standard packet switching network.
Also called connectionless. Opposite of circuit switched or connection-oriented.
See also virtual circuit, wormhole routing.
